I loved making The Imitation Game and it's really gratifying to hear the audience's response to the character that I play. It was just a little thing that I did because I really liked the film and I liked Benedict [Cumberbatch] and I loved Morten's [director Morten Tyldum] previous film, Headhunters. For me, it was something I did thinking, "Wow, this is a lovely quality piece of work."

[Before I Go To Sleep] script was a great journey with all the twists and turns that were kind of unexpected. I had to finish the script, and I thought if we can emulate this in the film, it's going to be a really good film.

In the film industry you never really know if all the various ingredients will come together - sometimes they do, and sometimes they don't. As an actor, you don't have much control over those things. It's a director's medium in that sense. All you can really do is minimise the risks of being involved in something that might not work and look for something that also suits you.

It's great to have the chance to play a character before he goes to the dark side, or the yellow side if you will. Normally, you don't get that opportunity. The narrative of a movie usually demands that you are that guy from the start.

The important bit for an actor is the actual shooting of it, because the minute the shoot ends, it's got nothing to do with you anymore.

If you think about Shakespeare, you remember Richard III and Macbeth before you remember Ferdinand, whose role is just to fall in love and be a bit of a wimp. I love the baddies. More important, though, is making the baddies somehow, weirdly, understood.

I'm very organized and tidy in my home life and I generally do something myself rather than farm it out to somebody else. I don't have an assistant or anything because I think I can do it myself.
